Well, i bought the game long ago on GOG, after trying it out as demo on Xbox live arcade (by the time it was called xbox live ARCADE, which means quite a while ago)
the game itself felt quite nice, to me... the whole 2D rotating to 3D fr platforming was indeed an interesting idea afaic... And the art was cute.
but by that time, the pc port was somehow rather unstable and buggy
i think i then heard a bit more about the game because of the movie about indie games that was bundled once in a humble bundle. i was indeed interested by the whole visiting the insides and behind the curtains of indie games from their makers' point of view; and fez was one of the featured games.
than, later after i had quit the game for a while, not because it was bad but because, you know, backlog and new releases... i stumbled upon some stuff Phil Fish said or wrote online. At first i didnt connect the guy to fez, frankly. I only managed to realize it was the same person from the movie later on.
then i did read and listened to more of the guy's speech... it was just completely "out of this world" for me, frankly.
Most of the time, i usually disconnect art from their makers, i mean if i like some music or movie or such, i dont care who are the persons behind. Well, usually... but that habit of mine has its threshold.
meanwhile i also learned that the whole development, support and patching of Fez was transferred to some team completely unrelated to the guy (and in fact, the pc port indeed improved a lot compared to what i had to cope with, back then)
So, basically, fez is a decent game, and it also had been within ends of more persons than JUST phil fish (after all, it was a two men project in the start, and surprisingly, in the indie game documentary i saw, mister Fish manages to lead the viewer into thinking the initial coder guy was a pure douchebag... But then, after seeing and listening to more fisheries, i slowly starts to doubt the other guy was THAT evil and jerk, frankly... after all, he had to cope with fish for 5 years), and the second team who took the project over at some point are not to be put in same bag as well...
but i can totally understand most people's feelings and how easy it is to associate Fez to Fish only,and as a consequence, to sort of penalize the game itself for the whereabouts of one of its co creators. I admit that would Fez was Fish creation alone all the time, his behavior so far would have go beyond my aforementioned threshold. However, i completely agree on one point: even if Fez is the work of more than one person, pc port especially, giving out money would sadly mostly go to Fish. On that regard, i sure strongly endorse the suggestion of someone here before, as in "buying it in a humble bundle and setting the money slider to zero on the Fez line"
TL;DR: I used to like Fez as a game, then i took a Phil Fish in the knee :) (but, he is not the only person involved in the game, and the other persons who worked on it initially and onto patching the pc port are not to be sorted in same category as this quite questionable fellow... And the game itself has its merits, gamewise)
